UNITED STATES PATENT OFFICE GEORGE J. FROST, OF TORONTO, ONTARIO, CANADA, ASSIGNOR OF ONE- HALF TO GEORGE DIOKSON, OF SAME PLACE.

WINDOW-BLIND FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 417,240, dated December 17, 1889.

(No model.)

To all whom it may concern:

Be it known that I, GEORGE JAMES FRosT, janitor, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented a certain new and Improved Window-Blind Fastener, of which the following is a specification.

The object of the invention is to providea simple, cheaply-made, and easily-applied fastener for securing a window-blind to its roller; and it consists, essentially, of a spring-metal clasp bent to conform to and spring onto a shade-roller, the said clasp having legs with spike-shaped toes designed to clasp and pierce the roller in such a manner as to firmly grasp and hold the blind in position.

Figure 1 is a view showing my blind-fastener in position on the roller. Fig. 2 is a detail of the fastener.

It Will be observed on reference to the drawings that my fastener is formed out of a piece of spring-wire, the said wire being folded in the center and the folded portion bent, as indicated, to form a spring-clasp A, which fits over and clasps the roller B, as indicated. The ends 0 of the wire extend at right angles from the fold, forming legs with spike-shaped toes D, as shown, which spikeshaped toes may be readily pressed into the Wooden roller B.

be necessary to straighten or adjust the blind upon the roller.

What I claim as my invention is As an improved article of manufacture, a clasp formed of a single piece of spring material folded near the center and bent to form a spring-clasp A, and the ends of the material extended at right angles to the clasp A in opposite directions therefrom and formed with spike'shaped toes D, substantially as shown and described, and for the purpose specified.

Toronto, April 13, 1889.
